The changing the dimension C may be made to meet part II] comprises a flat base plate I2 provided the condition for a different offset B (Figure 3).

v with suitable holes I3 for the reception of screws, Now according to .my invention, I provide a b l other Suitable means o Se uring the dependable and highly convenient means for achieving deceleration of the swinging door, or the like, or for achieving a limiting of the ex treme opening movement of the door, capable of functioning properly and appropriately no matter what change is made in the dimension C (Figure 2) to cope with changes in the offset B (Figure 3), and thereby I am enabled to achieve important and substantial advantages in the manufacture of hinges of this character or type. Accordingly, and bearing in mind the above described shape or configuration of the portion 2| of the hinge part II as is better shown 'in Figure 3, I provide a device generally indicated at 25 shaped as is better shown in Figure 4. Device 25 is substantially U-shaped; it has a base portion 26 with upstanding side arms 21 and 28, the latter being spaced apart so as to be snugly received between the upstanding posts |4|5 (see Figures 1 and 2). Moreover, side arm portions 2|28 are apertured as at 29 and 36, respectively (Figure 4), these apertures being dimensioned so as snugly to receive the pintle l3 and being spaced downwardly from the upper ends of the side arms 2'! and 28 by the samedistance that the holes |6 and I1 (Figure 2) are spaced downwardly from the upper ends of the posts 4 and I5, respectively. Moreover, the parts 21 and 28 are curved or shaped so that, when they become alined with and alongside of the posts l4 and I5, respectively, the former mate exteriorly with the latter and appear as a result unobtrusive and virtually as a part of the latter.

The member 25 (Figure 4) is made of a relatively heavy sheet metal, preferably of a springy material, such as spring steel, spring bronze, or

the like, of suitable hardness. Preferably, I employ spring steel which, with its temper drawn, may be relatively easily worked to give the member 25 the configuration and shape shown in Figure 4, after which it may be appropriately heated, heat-treated, or the like, to restore or to give it the desired resiliency.

Immediately above the apertures 29 and 36 (Figure 4) in the upstanding arms 21 and 28, the metal of the latter is stamped or pressed outwardly, as at 3| and 32, respectively, thereby forming substantial integral and strong lugs on the outer faces of the members 21 and 28. Now the upstanding posts l4 and I5 of the hinge part l6 (see Figures 1 and 2) are provided, on their inside faces and above the holes l6 and H, with vertically extending slots M and I5 respectively; these slots M and l5 are dimensioned to receive the projecting lugs 3| and 32 of the device 25 when the latter, prior to assembly of the hinge part I I and pintle l8 to the hinge part I6, is interposed between the posts 4 and I5 by sliding it downwardly, as viewed in Figures 2 and 3, in between the upstanding posts l4 and I5.

The end portion 2| of the hinge part furthermore, is given a width, as viewed in Figure 2, and hence a dimension along the axis of the hole 22 therein, such that it is snugly received in be- 5 tween the upstanding arm portions 21 and 28 of the device 25, and if the holes I6, 29, 22, 36 and I! are now alined and the hinge pin l8 thrust therethrough, the parts I0, 25 and ll become reliably assembled. Hinge part II may 7 freely pivot about the axis of the pintle l8 and hence relative to the hinge part I 0, but the interfitting of the lugs 3| and 32 with the slots M and i5 respectively, coupled with the fact that the hinge pintle I3 passes through both parts I0 and 25, insures that the latter part 25 cannot'pivot *as shown in Figures 2 and 4.

about the axis of the pintle 8 and becomes very securely anchored immovably to the part [6. The device 25 may thus be interfitted with hinge construction even though the hinge parts l6 thereof, particularly as to the dimension C of Figure 2, are different.

Now the horizontal base portion 26 (Figures 2 and 4) of the device 25 will be seen to be bowed upwardly to a suitable degree and, being inherently resilient or yielding, tends always to return to this upwardly bowed position or shape Substantially centrally thereof, the base portion 26 is provided with a recess conveniently taking the form of an aperture 33, for coaction with other parts about to be described.

At a suitable number, illustratively (but not by way of limitation) three, of points in the. arcuate part 23 of the portion 2| (see Figure 3) and midway of the portion 2| (see Figures 1 and 2) are projections which preferably take the form of hardened steel balls 34, 35 and 36. The latter are secured to the portion 2| of the hinge part I in any suitable manner, illustratively and preferably as shown in Figure 2, where the mounting of ball 36 is clearly shown. It will be noted that ball 36 is seated in a hole 2| formed or drilled radially into the portion 2| to a depth slightly greater than the radius of the ball 36, leaving a substantial portion less than half of the ball 36 projecting from the member 2|. The metal about the outer end of the hole 2| is then forced, in any suitable manner, inwardly against and about the ball 36 whereby the latter is held against coming out of the recess or hole.

Now the plane of the highest portion of the bowed base portion 26 of the member 25 (see Figures 2, 3 and 4) is spaced from the axis of the pintle l3 by a distance which is slightly greater than the radius of curvature of the arcuate surface 23 (Figure 3) of the hinge portion 2| but less than'the radius drawn from the axis of the pintle i8 to the outermost part of any one of the balls 34, 35, etc., the balls being, of course, as is now clear, positioned in an arc of a circle whose center is the axis of the pintle I8.

Accordingly, and viewing more particularly Figure 3, as the door is swung in opening direction and hence to swing the hinge part II in counterclockwise direction, as viewed in Figure 3, relative freedom of swinging takes place throughout an angle approximating 90 degrees, by which time ball 34 bears against the upwardly bowed base portion 26 and has todistort the latter toward a straight line or unbowed relation; since the device 25 is relatively powerful, a certain amount of energy of the swing of the door is consumed, in tending to unbow the member 25. But the reactions resulting from this unbowing of the portion 26 are taken up in or by the pintle I8 itself or in or by the hinge construction per se, being transmitted thereto by the side arm portions 21, 28.

The door continues to swing and the ball 34 snaps into the recess 33 and, if the energy of swing of the door has been dissipated, the door is held in that position.

If, however, the deceleration of the door has not proceeded sufficiently far in this first step, the door will continue to swing, snapping the ball 34 out of the recess 33, thereby again tending to unbow the device 25 but as the ball 34 continues to move about the axis of the pintle 34 and hence to move away from the base portion 26 of the device 25, the next ball, namely ball 35, is brought iii into engagement with the device whose stiff resiliency it has to overcome, thus further dissipating the energy of swing of the door and thus achieving the next stage of deceleration.

By the time ball is juxtaposed to the recess 33, the base portion 26 snaps upwardly and ball 35 finds its seat in the recess 33, thus holding the door in that position if by that time the energy of swing of the door has been completely dissipated. If not, ball 35 is moved out of the recess 33, just as was ball 34 as above described, and ball 36 comes into coaction with the part 26, just as had ball 35 as just described.

Also, the side arm portions 2'! and 28 (Figures 1, 2 and 4) of the device 25, being preferably made integrally with the base portion 26 and hence being preferably made of the same metal as the latter, are thus of excellent wear-resisting qualities and, being non-rotatively related to the hinge part H], they dependably protect the posts l4 and ill of the latter against wear due to the swinging relative thereto of the hinge part II.

Furthermore, it will be seen that the construction lends itself to rapid disassembly for replacement or repair of any part.

It will thus be seen that there has been provided in this invention a hinge construction in which the various objects hereinbefore noted, together with numerous practical advantages, are successfully achieved, and that the construction is well adapted to meet the varying conditions of hard practical use.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense. a
